I am now considering brewing an imperial stout to be aged 6-12 months before tasting it. I am just wondering where the 6-12 month aging process is supposed to take place, in secondary or in the bottle? I am concerned that after 12 months in secondary carbonating may be a problem at bottling?

Maybe two weeks in primary, a month in secondary and then bottle? I am just not sure and I don't want to put all the $$$, time and effort into such a big beer and ruin it. Any advice would be appreciated!
